Figure 6
Percentage uncertainties (standard errors) of the foil attenuations versus nominal monochromator energy. Uncertainties typically varied from 0.002% to 0.14% where the larger uncertainties were contributed by the thickest foil of 275 µm used in the 17–20 keV energy range. The uncertainties of the attenuations of the other foils were no larger than 0.05% in the 6–17 keV energy range except at 13 keV reaching up to 0.14% due to beam clipping at that point. With the 10 µm- and 12 µm-thick foils, the uncertainties were relatively high at energies below 6 keV.
